Rice University scientists today unveiled a method for the industrial-scale processing of pure carbon-nanotube fibers that could lead to revolutionary advances in materials science, power distribution and nanoelectronics. The result of a nine-year program, the method builds upon tried-and-true processes that chemical firms have used for decades to produce plastics. The research is available online in the journal Nature Nanotechnology.
The new process builds upon the 2003 Rice... Read Full Story
Researchers at Rice University have announced the discovery of a new breakthrough method for producing carbon nanotubes in bulk fluids. Rice’s new nanotube “stew” could spur the inexpensive mass production of carbon nanotube-based products, much like the plastics industry employed bulk loads of melted polymers as a cheap base for making everything from medical equipment to polyester shirts to plastic bags, and countless other things in between. Rice’s nanotube research was sponsored in... Read Full Story
CHICAGO (Reuters) - In determining the safety of improbably small materials known as nanoparticles, special properties associated with some of the very smallest particles may be the key, scientists said on Sunday. Nanotechnology, the design and manipulation of materials thousands of times smaller than the width of a human hair, has been hailed as a way to make strong, lightweight materials, better cosmetics and even tastier food. But scientists are only starting to look at the impact such... Read Full Story
Scientists at the California Institute of Technology (Caltech) have uncovered the physical mechanism by which arrays of nanoscale (billionths-of-a-meter) pillars can be grown on polymer films with very high precision, in potentially limitless patterns. This nanofluidic process -- developed by Sandra Troian, professor of applied physics, aeronautics, and mechanical engineering at Caltech, and described in a recent article in the journal Physical Review Letters -- could someday replace...

When people think about building things with carbon nanotubes or with carbon nanotube enhanced materials they need to know that there is not much production of carbon nanotubes. There is less than 1000 tons/year of carbon nanotubes being produced and most of that is in a form that is like an unsorted powder. The material that has been woven into threads or sheets will soon be tens of tons per year and that macro scale material is not as strong at the macroscale. The cost of... Read Full Story
Researchers at the Institute for Physiological Active Compounds in Kharkiv Ukraine have in the past two years shown that hydrated fullerenes (C60) HYFNs have a positive effect on both plant and animal growth. One day old chicks, who are feed water with nano levels of fullerenes are healthier, weigh more and don't need antibiotics. (Hydrated Fullerenes have anti-viral and anti-bacterial properties) Similarly wheat seedlings dipped in water laced with hydrated fullerenes, grow faster and... Read Full Story
With potential adverse health and environmental effects often in the news about nanotechnology, scientists in Arkansas are reporting that carbon nanotubes (CNTs) could have beneficial effects in agriculture. Their study, scheduled for the October issue of ACS Nano, found that tomato seeds exposed to CNTs germinated faster and grew into larger, heavier seedlings than other seeds. That growth-enhancing effect could be a boon for biomass production for plant-based biofuels and other... Read Full Story
HONG KONG (Reuters) - Seven young Chinese women suffered permanent lung damage and two of them died after working for months without proper protection in a paint factory using nanoparticles, Chinese researchers reported on Wednesday. They said the study is the first to document health effects of nanotechnology in humans, although animal studies in the past have shown nanoparticles could damage the lungs of rats. "These cases arouse concern that long term exposure to nanoparticles without... Read Full Story
HONG KONG (Reuters) - Seven young Chinese women suffered permanent lung damage and two of them later died after working for months without proper protection in a paint factory using nanoparticles, Chinese researchers reported. Nanotechnology, or the science of the extremely tiny, is an important industry. One nanometer is one-billionth of a meter while nanoparticles measure between 1 to 100 nanometers. Apart from medicine, it is used in products like sporting goods, tires and electronics and... Read Full Story
